Unpack the installation files into the installation directory

The installation directory stores Oracle Empirica Signal components during the installation process.

Perform these steps using the non-privileged user account on the application server.

Note:

If you have previously installed Oracle Empirica Signal 8.x or 9.0.x on the same application server, before executing the steps below, rename the old Signal_Install directory. For example, change its name to Signal_Install_old.

Unpack the Signal_Install-9_1_0_0_XXX.tar.gz file into a directory that is accessible to the Oracle WebLogic Server software, for example:
```
$ cd /u01/stage
$ tar xvf /u01/stage/Signal_Install-9_1_0_0_XXX.tar.gz
```
The /u01/stage/Signal_Install directory is created.

Note:
In this document, <INSTALL_DIR> refers to the directory created in this step. The document assumes that you are installing to this directory.
Unpack the contents of the Signal-9_1_0_0_XXX.zip file into the directory, for example:
$ unzip Signal-9_1_0_0_XXX.zip -d /u01/stage/Signal_Install/Signal
If you use Oracle Empirica Topics, unpack the TopicsService-9_1_0_0_XXX.zip file into the TopicsService subdirectory in the installation directory, for example:
```
$ unzip TopicsService-9_1_0_0_XXX.zip -d
/u01/stage/Signal_Install/TopicsService
```
Note:
If you have previously installed Oracle Empirica Signal 8.x or 9.0.x on the same application server, before executing the steps below, rename the old Database directory. For example, change its name to Database_old.
Unpack the Signal-9_1_0_0_XXX-Database.zip file:
1. Create a Database directory:
  $ mkdir /u01/stage/Database
2. Unpack the contents of the Signal-9_1_0_0_XXX-Database.zip file into the directory, for example:
  $ unzip Signal-9_1_0_0_XXX-Database.zip -d /u01/stage/Database
